Drug Use Investigation of Kaletra

• Total Number of Patients With Adverse Drug Reactions [ Time Frame: During the course of the survey period up to Year 8 ] [ Designated as safety issue: Yes ]
  Number of patients with adverse drug reactions, defined as adverse events for which the causal relationship with Kaletra was something other than "not related" by the investigator (i.e., "probable," "possible," or "unclear"), that occurred in ≥ 5% of patients. Adverse drug reactions are reported by preferred term and inclusive of all those reported at each visit. Although a patient may experience a particular preferred term more than once, each patient was counted only once for each preferred term.
• Cluster of Differentiation 4 Lymphocyte Count (CD4) [ Time Frame: Baseline (Month 0), every 3 months thereafter up to Month 12 and every year thereafter up to Year 8 (Month 96) during the course of the survey period ] [ Designated as safety issue: No ]
  The evolution of patients' CD4-positive (CD4+) T-lymphocyte counts after starting treatment with Kaletra was assessed by measuring the number of CD4+ cells at baseline and each subsequent study visit. CD4+ counts are reported as the number of CD4+ cells per cubic millimeter (cmm) and presented by the mean at each visit. Only observed cases were included in analyses; no data were imputed. n = xx, xx is the number of patients naive to previous antiretroviral treatment and those that were not who had CD4+ T-cell counts available for analysis at each study visit.
• Mean Number of Human Immunodeficiency Virus (HIV) Ribonucleic Acid (RNA) Copies Per Milliliter (mL) Using a Logarithmic (Base 10) Transformation at Each Visit [ Time Frame: Baseline (Month 0), every 3 months thereafter up to Month 12 and every year thereafter up to Year 8 (Month 96) during the course of the survey period ] [ Designated as safety issue: No ]
  Number of HIV RNA copies per mL is presented by the mean per visit for patients that were naive to previous antiretroviral treatment and those that were not. HIV-RNA data reported as < 400 copies/mL were considered 399 copies/mL in calculations. The mean and standard deviation of HIV-RNA levels were thus calculated after logarithmic (base 10) transformation (log10 399 is 2.6). Only observed cases were included in analyses; no data were imputed. n = xx, xx is the number of treatment-naive, treatment-experienced participants who had CD4+ T-cell counts available for analysis at each study visit.
• Number of Patients Included in Each Center for Disease Control and Prevention (CDC) Classification Category for HIV-infected Adults and Adolescents [ Time Frame: Baseline (Month 0) and following last treatment dose during the course of the survey period ] [ Designated as safety issue: No ]
  Number of patients in each CDC category at Baseline (last assessment within 30 days prior to first dose of Kaletra) and after treatment. CDC categories defined as: Category A (asymptomatic acute HIV infection), Category B (symptomatic HIV infection; not Categories A and C), Category C (acquired immunodeficiency syndrome [AIDS] indicator status), Class P-0 (children not confirmed for HIV infection), Class P-1 (children with asymptomatic HIV infection), or Class P-2 (children with symptomatic HIV infection).

• Evaluation of adverse event (occurrence of adverse event (yes or no), date of onset, diagnosis or definite symptom, details of symptom/course/intervention, seriousness, intensity, outcome, relationship to disease and drugs used) [ Time Frame: During survey period (every end of March) ] [ Designated as safety issue: Yes ]
• Cluster of differentiation 4 lymphocyte count, number of Human Immunodeficiency Virus-ribo nucleic acid copies, Centers for Disease Control and Prevention classification [ Time Frame: During survey period (every end of March) ] [ Designated as safety issue: No ]

This non-interventional, post-marketing observational study was conducted to obtain data, such as safety and effectiveness, from the use of lopinavir/ritonavir (Kaletra) in clinical practice and investigate the necessity to conduct a follow-up post-marketing clinical study in Japan.
